Patented Mar. 7, 1939 UNITED sm'r FORM. FOR CONCRETE STRUCTURES Mike Winandy, Richmond, Ind. Application February 1, 1937, Serial No. 123,422 3 Claims. (01.25-118) This invention relates to forms for monolithic concrete structures, and more especially to forms used in the construction of concrete benches for use in greenhouses and the like.

5. The principal object of the invention is the provision of a combination of parts which will expedite the assembly of the necessary forms required to efficiently and economically construct the benches.

Another object of the invention is the provision. of members which are simple of construction, economical to manufacture, and which, when assembled, are rigid and substantial.

Another object of the invention is the provision of means for supporting the forms without the necessity of providing expensive equipment.

Still another object is the provision of form members which are extremely light in weight, and which thereby, minimizes the cost of trans portation from one location to another.

A still further object of the invention is the provision of clamping members which rigidly maintain the side members of the forms in fixed relation with each other when assembled.

Other objects and advantages of the invention will suggest themselves in the course of the following description, and that which is new will be pointed out in the appended claims.

The most satisfactory and preferred manner of carrying out the principles of the invention in a practical, economical, and efficient manner is. shown in the accompanying four sheets of drawings, in which;

Like characters designate like parts throughout the several views.

In order that the construction and advantages of the invention may be more fully understood and appreciated, I will now take up a detailed description thereof, in which the same will be more fully set forth.

In the drawings, A designates the vertically extending sides of the completed bench, B designates the floor portion, C designates the post members, with C and C designating the upper and lower portions respectively of the post members, all of which are formed of monolithic construction. D designates drainage apertures formed vertically through the floor of the completed bench.

Now referring to the form members and the construction in detail, I designates vertically positioned supporting members with each being comprised of a length of pipe which is driven into the earth with the upper end thereof projecting above the earth. The members I are arranged in rows, with each of the members being positioned in substantial alignment with other like members of the same row. Two rows of the members I are required to support the form members, with each of the rows being arranged in parallel relation with the other.

2 designates the supporting clamp members, the same being positioned on the vertically positioned supporting members, and being rigidly secured thereon by means of the threaded set screws 3. The clamp members 2 are formed substantially circular in shape with a portion thereof being omitted, and forming a space thereby for the purpose of positioning the clamps 2 on their respective supporting members I, all as shown in Figures 7 and 14. A lug .4 is formed integrally with the clamp member 2, and projects outwardly therefrom. On the side opposite the lug 4 is a threaded aperture formed through the body of the clamp member for the reception of the threaded set screw 3. Opposite the set screw 3, and adjacent the lug 4, an indenture 2' is formed for the purpose of allowing the respective supporting pipes I to contact the inner surface of the clamp 2 .attwo places or points, with the set screw 3 bearing against the opposite side of the supporting pipe, and thereby maintaining the clamp member 2 in rigid relation to the supporting pipe I, as shown in Figure 7.

The comparatively long pipes 5 are positioned longitudinally with relation to the proposed benches, with the same resting in the concave portion 4' of the lugs 4, as shown in Figure 6. The pipes 5 provide supports for the end portions of the transverse supporting members 6.

The transversely positioned members 6 are placed on and supported by each of the pipes 5 With the end portions of the members 6 extending outwardly beyond the pipes 5, as shown in Figures 5, 6 and 17."

Floor members 1 are arranged longitudinally between the transverse members 5 with the end portions of the floor members I meeting each other and resting on the members 6. Drainage aperture forms 8' are provided and secured through 'the floor members I by means of the bolts 9, and are arranged thereon at intervals to provide the most'efiicient draihageof the moisture which accumulates within the finished benches when the same are in practical use.

The outer side members Ill, of the forms, are

formed of comparatively light gauge sheet metal,

with the lower portions I thereof being turned outwardly at right angles to the vertical portions thereof. The outer edges II'I of the portion ID are turned upwardly with relation to the respective portions III, and provide stiffness thereto. The upper portions IIJ of the member II] are also turned outwardly in a similar manner to the portions Ill, and are provided with the turned-down 1y disposed portions I2.

portions III which provide stiffness thereto. The members I Ii are rigidly secured to the floor members through the portions II! by means of the threaded screws I I, as shown more clearly in Figures 6 and 17.

The inner form members I2 are formed of sheet metal similar to the outer side members If], and have inwardly extending portions I2 formed at the upper edges thereof, with the downwardly extending flanges I2 being formed along the inner edges of the portions I 2 The angular inwardly extending portions I2 are formed at the lower edges of the members I2, with the inwardly extending portions I2" being formed at the lower edges of the portions I 2' and at right angles with relation to the vertical- It will be noted that the members I2 do not extend as far downwardly as the members I0, and thereby providing a gauge for the thickness of the floors of the completed benches. It will also be apparent that the upper surfaces of the drainage aperture forming members 8 are on the same approximate level as the under surfaces of the portions l2" of the members I2, with the upper surfaces of the members 8 also forming a gauge for the upper surfaces of the floors of the completed benches. Each of the members 8 has countersunk apertures 8' formed through their upper surfaces for the reception of the heads of the bolts 9, and thereby present an unobstructed top surface for the members 8, all of which is clearly shown in Figure 6.

Clamps are provided for spacing the inner members I2 in fixed relation to the outer members II], with eachof the clamps comprising two members [3 held rigidly together by means of a bolt I I. Each of the clamp members I3 is identical with each other, and the description of one of the members will sufiice for the other. The clamp member I3 has the projecting portions I3 and I3 which serve as spacers, and definitely fix one of the members I3 in spaced relation to the companion member I 3 when assembled and secured together by means of the threaded bolt I4. The members I3 have an aperture I3 formed therethrough for the reception of the bolts I4, with the outermost end portion I 3 of the aperture being formed square in cross section, as shown in Figure 24, for the reception of the square shoulder I4 of the bolt I4, the same being for the purpose of preventing the bolt from turning as the threaded nut I I" is tightened thereon. Each of the clamp members I3 has the upper and lower lugs III and I3 formed thereon, with these lugs being adapted to bear against the respective side form members I0 and I2. A downwardly projecting lug I3 is formed on each side of the member IS with the same being adapted to bear against the upper portions Ill and I 2 of the members In and I2 respectively, and with the respective portions II) and I2 extending downwardly in the apertures I3 of the members I3.

Pivotal wedge members I are provided to rigidly maintain the members I0 and I2 in fixed relation with each other, and with the respective members IS. The wedge members I5 are pivotly secured, through their lower portions, to the members I3 by means of rivets I6, and have the camshaped surfaces I5 formed at the upper portions thereof, with the surfaces I5 being adapted to bear against the under side of the respective portions II'I and I2 A projecting lug I5" is formed on the member I5, near the lower end portion thereof, and provides a stop for the member I5 when the same is in disengaged position, as

. shown in Figure 23. When the wedge members.

l5 are inwed'gedposition against the under sidesof; the portions Ill and H the action thereof causes the upper surfaces of the portions l and I2 to be pressed tightly against the under surfaces of. the downwardly projecting lugs I3 and thereby securely clamping the members [0 and l2 in: their respective members l3. It will also be apparent that one of 'the side portions of the wedge members l bears laterally against the downwardly extending portions 6 and I2 with the action thereof causing the vertical portions l0 and [2 respectively to be maintained in contact; with the lugs Is and' Q3 of the members I3. It will be noted: that the lugs i3 and it" provide fixed. spacing of the members l3 without the necessity of providing any other gauging means, and. with these means, the form members I 0 and I2 are automatically maintained in spaced relation with each other.

The post members C of the completed benches are formed by means of the members ll, two of which are used for each post member.. Each of the members H has an outwardly-turned flange I1 formed at the upper edges thereof, with the flanges l1 being adapted to rest on the end portions of the adjacent floor members I. The vertical edges of the members I! are each provided with outwardly extending flanges H, with the same having apertures formed therethrough for the reception of the bolts l8 which secure the members I! together at the outer edges thereof. It will be noted that the members I! are not secured to the members I, but are suspended therefrom by means of the flanges ll extending over the adjacent edges of the members I. The spaces between each pair of the post-forming members are filled by means of the filler members I9 which also lap over the end portions of the adjacent end portions of the members I, as shown in Figures 8 and 9. The post-forming members I! and the filler members l9 are formed of comparatively light gauge sheet metal.

It will be apparent from Figures 1, 2 and 4 that the lower end portions of the members U do not extend downwardly to the surface of the earth. When the forms are being filled with concrete, the same is allowed to pass downwardly through the members I1, and to form piles of concrete from the surface of the earth upwardly to the lower end portions of the members H, and thereby forming bases C for the posts C.

It is necessary to provide expansion joints in the benches at approximately intervals of twentyfive or thirty feet in order to allow for longitudinal expansion and contraction of the benches, and the expansion. joint members 20 are provided for this purpose. The members 20 are formed U-shaped, as shown in Figures 19 and 20, and are formed of light gauge sheet metal which will provide for compression when expansion of the benches occur. The members 20 are left in the benches after the same are built.

placed. across the pipes 5 with their outer endportions projecting therebeyond. The floor members t are laid from one of the members 6 to the next adjacent member 6 with each end of each member 1- resting on a transverse member 6', with the drainage aperture forming members 8 having been previously secured through the members 1 by means of the respective bolts 9. The outer members I only are rigidly secured to: the members B by means-of nails or other suitable means. The outer side members H! are rigidly secured to the outermost members I through the portions If! by means of the threaded screws l l. The outer clamp members l3 are arranged along the upper edges of the members Ill at the desired intervals, a-fter which the inner side members [2 are provided with their respective clamp members l3, and are placed into position with relation tothe outer member ll], after which the bolts M are extended through the apertures [3 of both'halves of the clamp members and the respective nuts I4" are threaded onto the threaded end portions of the bolts l4 and tightened against the respective members l3. When the clamp members l3 are tightly drawn together by means of the bolts l4 and the threaded nuts M", it is apparent that the projecting lugs l3 and I3" provide predetermined spacing means for the members If] and I2. After the two members l3 have been secured together, the pivoted Wedge members l5 are swung upwardly with the surfaces I5' contacting the under surfaces of the respective portions Ill and I2 and thereby tightly securing the portions H3 and M against the under sides of the lugs l3.

After the forms have been filled with concrete, and the same has set the required length of time,

and with the forms being ready to be taken.

therefrom, the bolts I4 are removed from the clamps l3 and the inner form members, together with the respective clamp members I 3, are removed. The threaded screws H, by which the members ID are secured to the respective floor members 1, are removed, and the members it] together with the respective clamp members l3 are removed from the floor members '7. The set screws 3 are loosened, and the clamps 2 are removed from their respective vertical pipe members I, allowing the members 5, 6 and 1 together with the drainage aperture forming members 8 to drop downwardly from the completed bench, after which the parts of the forms are disassembled. After the forms have been removed, the bolts l8 are removed from the flanges ll" of the members l1, and the halves of the members I! are then removed from the completed posts C.

I desire that it be understood that the concrete may be reinforced with rods or wires in the conventional manner, or the benches may be formed without the usual reinforcements.

I also desire that it be understood that minor changes may be made in the several details, and in the arrangement of the parts herein shown and described, insofar as the changes may fall Within the scope of the appended claims.

Having now fully shown and described the invention, what I claim, and desire to secure by Letters Patent of the United States, is:

1. In forms for concrete structures, a vertically disposed outer side member having an outwardly turned flange formed on the lower portion thereof with the flange being secured to floor members and with the upper portion of the outer side member turned in a horizontal position and at right angles to the vertically disposed portion and with the outer edge of the upper horizontal portion being turned downwardly, a clamp member removably secured on the upper portion of said side member, a wedge member forming a part of said clamp member and pivotly secured thereon and adapted to wedge against the under side of the upper portion and rigidly securing the same thereto, and with the clamping member supporting and positioning an inner side member in predetermined spaced relation with the outer side member.

2. In a form for concrete structures, an outer side member and an inner side member, with the lower portion of the outer side member being rigidly secured to floor members, clamping members, with each being comprised of two identical halves secured together by means of a threaded bolt passing through both halves thereof, a wedge member p-ivotly secured in each half of each clamp member with a portion of each of said wedge members being adaptedto wedge against verse members, outer side members rigidly secured to said floor members and extending upwardly therefrom, inner side members supported from said outer side members, and means for supporting'said inner side members, in predetermined fixed relation to said outer side members.
